yylloc reflects the location of the current token. Its end
point does not necessarily coincide with the current scanner
point.
|
|
Remove the grecs_current_locus_point variable. Use yylloc.end directly.
For git-parser.c and path-parser.c, provide a static replacement.

The adjacent string concatenation feature doesn't work well with
multiple-argument statements. The common example (found in GNU
pies) is the "env" statement:
env "PATH=/sbin:$PATH" "PRELOAD=true"
The intent was to pass it two arguments, but in fact they get
concatenated into one.
To control this, the grecs_parser_options variable is introduced.
If it has the GRECS_OPTION_QUOTED_STRING_CONCAT bit set, adjacent
string concatenation is enabled. By default it is disabled.
The GRECS_OPTION_ADJUST_STRING_LOCATIONS bit controls the way the
quoted sring locations are computed. If it is set, the beginning of
the string is counted at the first character after the opening double
quote, and its end at the character immediately preceding the closing
double quote. Otherwise, both double-quote characters are included in
the location (the default).
The change is backward incompatible.
