As noted by cem in r338035, coccinelle invokes diff(1) with the -B flag. This was not previously implemented here, so one was forced to create a link for GNU diff to /usr/local/bin/diff Implement the -B flag and add some primitive tests for it. It is implemented in the same fashion that -I is implemented; each chunk's lines are scanned, and if a non-blank line is encountered then the chunk will be output. Otherwise, it's skipped.

-y:
|
|
* soc implemented it via calling sdiff directly, but some options are
|
|
incompatible so it is fragile
|
|
* just recommend the user to run sdiff directly and do not implement it
|
|
* make a libsdiff and use that directly to avoid duplicating the code
|
|
|
|
to be implemented:
|
|
--horizon-lines
|
|
--ignore-tab-expansion
|
|
--line-format
|
|
|
|
Will probably be not implemented:
|
|
--GTYPE-group-format (partially implement - minimal)
|
|
--LTYPE-line-format
|
|
--help (We have a manpage already)
|
|
--suppress-common-lines: depends on -y (won't be implemented, as it conflicts
|
|
the way sdiff expects it and in any case we have sdiff for that feature)
