check in for marc

rework errno processing to be more consistent and to set in the correct
node; don't chdir back up if unable to chdir down; preserve the cd error
value to set in each node of the directory that is read

index/rindex return a pointer to the character, not the character

Corrected compar() fn type to const FTSENT ** rather than
const FTSENT *.

statb is now a pointer, statp

see accpath, used by fts_stat

adjust tree pointers when realloc space; add FTS_DOT; don't allocate
stat structures unless user needs them;

lots of minor rewording; add FTS_DOT, fix errno reporting

set errno on FTS_DNR

init the pointer if not passed the array of weightss

fts_children needs to return user's logical hierarchy;
make fts_error user visible, add wording to fts_children description

fts_children needs to return user's logical hierarchy;
change fts_cderr to fts_errno; change fts_children to recognize call before
fts_read called; change fts_stat to set fts_errno on error

KNF

lint and KNF

typo

add fts_cycle for cycles, quit overloading fts_link; minor wordsmithing

weren't checking high enough in the tree for cycles; get rid of the
savelink stuff and just add another pointer field to the FTSENT structure

ANSI C: tolower/toupper only work if isupper/islower is true for char

SEEDOT replaced FTS_DOT completely
