config: correct '**' matching in includeIf patterns
The current wildmatch() call for includeIf's gitdir pattern does not
pass the WM_PATHNAME flag. Without this flag, '*' is treated _almost_
the same as '**' (because '*' also matches slashes) with one exception:
'/**/' can match a single slash. The pattern 'foo/**/bar' matches
'foo/bar'.
But '/*/', which is essentially what wildmatch engine sees without
WM_PATHNAME, has to match two slashes (and '*' matches nothing). Which
means 'foo/*/bar' cannot match 'foo/bar'. It can only match 'foo//bar'.
The result of this is the current wildmatch() call works most of the
time until the user depends on '/**/' matching no path component. And
also '*' matches slashes while it should not, but people probably
haven't noticed this yet. The fix is straightforward.
