wildmatch: fix "**" special case
"**" is adjusted to only be effective when surrounded by slashes, in
40bbee0
(wildmatch: adjust "**" behavior - 2012-10-15). Except that
the commit did it wrong:
1. when it checks for "the preceding slash unless ** is at the
beginning", it compares to wrong pointer. It should have compared
to the beginning of the pattern, not the text.
2. prev_p points to the character before "**", not the first "*". The
correct comparison must be "prev_p < pattern" or
"prev_p + 1 == pattern", not "prev_p == pattern".
3. The pattern must be surrounded by slashes unless it's at the
beginning or the end of the pattern. We do two checks: one for the
preceding slash and one the trailing slash. Both checks must be
met. The use of "||" is wrong.
This patch fixes all above.
