Set_Variable, Export, etc.) to new ones (ReadVariableGS, SetGS, ExportGS,
etc.) in many places; there are still a few more to change. This change
removed the 256-character limit on strings retrieved by these routines,
such as the value of environment variables. (PR # 9).
At startup do not set $TERM to gnocon if it is already set.
Removed the df command (from builtin.asm).
Defined macro incad to increment a 4-byte address, checking for overflow;
replaced instances of "inc ptr" with "incad ptr".
Changed column offset table to use a 1-word rather than 1-byte entry. This
resolves PR#14 (hash wouldn't print beyond first 256 filenames).
Fixed defect in unalias (alias.asm) where the double quote portion of the
scanner would look for a terminating single quote. This resolves PR#69.
Changed default order for copying files in $PATH dirs into executable list,
so earlier paths files are found first.
Added environment variable flag $OLDPATHMODE to make gsh behave in the old
(backwards order) way when necessary.
Discard duplicate filenames when hashing.
Fix PR#73: directory in $PATH with escaped space (\ ) is not searched.
* 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.
