`factmove` arguments now behave more sensibly in that:
* `factmove #channel keyword global keyword` now properly moves/renames
factoids to global channel
* `factmove #channel keyword #channel global` renames the factoid to `global`
* `factmove #channel keyword newname` renames the factoid to `newname`
* func sed no longer trims leading whitespace
* quoted text no longer trims leading whitespace
* no longer convert tabs to spaces in output
* no longer condense adjacent whitespace together in output
* set `preserve_escapes` to 0 in guest/_c_base.pm so escapes are stripped in:
<pragma-> ,show testcargs
<candide> [global] testcargs: /code c11 printf("/say args: " ); while
(*++argv) printf("[%s] " , *argv);
<pragma-> ,testcargs foo\'bar baz\'qux
<candide> args: [foo\'bar] [baz\'qux]
to produce the desired output of:
<candide> args: [foo'bar] [baz'qux]
* set `keep_spaces` to 1 in host/_default.pm since it turns out that in some
languages unquoted spaces are significant, e.g. in `sh ${1% *}` to strip
text following two spaces. Without `keep_spaces` enabled, `sh ${1% *}`
becomes `sh ${1% *}` and strips all text following one space instead of two.
E.g.:
<pragma-> show testcargs
<PBot> [global] testcargs: /code c11 printf("/say args: " ); while (*++argv) printf("[%s] " , *argv);
<pragma-> testcargs 'hello''world' 'how are 'you today
<PBot> args: [helloworld] [how are you] [today]
Previously, adjacent 'foo''bar' would end up as 2 args like [foo] [bar]. Now
they are properly concatenated into one [foobar] argument.
This also fixes the cases of whitespace being inserted after quoted arguments.
general.debugcontext: filter out cmdlist and arglist
Core/Applets: log applet start/stop and duration
Core/ProcessManager: fix potential race-condition with $context object
Core/Interpreter:
* expand pronouns before command-substitution
* attempt to find current channel's factoid instance for metadata
* remove duplication of command history in command-substition
* terminate pipe/substitution processing when protecting self
Core/Factoids: limit -url contents to 250kb
Same-player ships will no longer be aligned end-to-end in the same orientation
to appear like one long ship.
There will no longer always be an even amount of horizontal and vertical ships
for each player.
