Changes for gsh version 2.0d8:
Fixed several mutual exclusion problems, including a particularly nasty
one that would cause gsh to loop forever inside the memory manager. (You
could identify this one by the "BRA (-23)" at the bottom of the infinite
loop.)
Fixed the string vector print routine to properly handle all numbers of
entries in the hash table. Previously, it would always print duplicate
entries if there were < 6 commands hashed, and would sometimes print
duplicates (depending on previous contents of an internal table) for
other numbers of commands.
gsh would wait on background processes started from an exec file
(executed, not sourced). Now the exec file does not wait on the process,
but the background process is not associated with the parent shell after
the exec file terminates.
Made gsh globbing work more like csh: if none of the requested patterns
are found, print "No match" and exit.
At startup, if /etc/glogin, $HOME/glogin, or $HOME/gshrc does not exist,
don't report a "file not found" error message. (PR#100)

Major changes to gsh with this checkin:
* When ~ is parsed and next character is a delimiter, make sure contents
of expanded $HOME match the user's delimiter.
* When wildcard patterns don't match, rather than terminating the command
gsh now prints "No match: <pattern> ignored" and passes the command line
minus the unmatched patterns on to be executed.
* Modified echo command so it doesn't add a blank to the end.
* Make "clear" and "source" built-ins non-forked commands. Unforking
"source" allows prefixes to be set in files that are sourced.
* Add loop to parse a single command (removing leading whitespace) before
sending it off to be expanded and executed. Skip null lines and comments
at this level. This allows later commands that depend upon variables set
in the 1st command to work; e.g.: set t_num=1 ; echo "Test number $t_num"
Also fixes problems seen when tab was first character of multiple lines.
* Initialize environment variable flags at startup (for echo, nodirexec,
nonewline, noglob, nobeep, pushdsilent, term, and ignoreeof). Set
flag when env var is set in upper or lower case (formerly, only worked
with lower case).
* Lots of places two-word addresses are incremented using inc, without
checking for overflow into the high-order word. As these are discovered,
they are changed to use adc on both words.

Changes for gsh version 2.0d5:
Add quotes around null parameters from the command line so they will be
parsed properly (resolves PR#84).
Output piped to an unfound command caused gsh to terminate, due to an
interface change to the GNO 2.0.6 version of getpgrp(2): it now returns the
process group of the caller. To get the process group number for the
pid passed as a parameter pid, the call has to be made to _getpgrp(2).
In addition to fixing invoke.asm, updates were also made in jobs.asm.
When directory stack is full, pushd, reports a new error message: 'pushd:
Directory stack full'. (Previously, 50 pushds would cause a crash.)
When parameter passed to "pushd +n" is <= 0, report a new error message:
'pushd: Invalid number'. (Previously, tried to chdir to the parameter.)
When a command appends to stderr (e.g., echo test >>&/tmp/err), stdin was
closed, due to errappend being defined as pipefds+2 rather than pipefds+4
in cmd.asm.
When there was an error reading stdin, gsh went into an infinite loop of
beeping and requesting more input. Changed getchar (in stdio.asm) and
GetCmdLine (in edit.asm) to report the error and terminate.
Code in cmd.asm set and reset handler for signal SIGSTOP (17). This makes
no sense, since there cannot be a handler for SIGSTOP. This was changed
to set and reset signal SIGTSTP (18) since that handler is used by gsh.
The error message "specify a command before redirecting" was never
caught by the invoke() subroutine because the next higher routine,
command(), checked for argv==0 before calling invoke(). The error
message was moved into command().
