wildmatch: advance faster in <asterisk> + <literal> patterns
Normally when we match "*X" on "abcX", we call dowild("X", "abcX"),
dowild("X", "bcX"), dowild("X", "cX") and dowild("X", "X"). Only the
last call may have a chance of matching. By skipping the text before
"X", we can eliminate the first three useless calls.
compat, '*/*/*' on linux-2.6.git file list 2000 times, before:
wildmatch 7s 985049us
fnmatch 2s 735541us or 34.26% faster
and after:
wildmatch 4s 492549us
fnmatch 0s 888263us or 19.77% slower
