fts: introduce FTS_VERBATIM This gives clients the option to disable stripping of trailing slashes from input path names during fts_open initialization. The recent change v0.0-7611-g3a9002d that made fts_open strip trailing slashes from input path names had a negative impact on findutils that relies on the old fts_open behavior to implement POSIX requirement that each path operand of the find utility shall be evaluated unaltered as it was provided, including all trailing slash characters. * lib/fts_.h (FTS_VERBATIM): New bit flag. (FTS_OPTIONMASK, FTS_NAMEONLY, FTS_STOP): Adjust. * lib/fts.c (fts_open): Honor it.
