match: support rooted globs in hgignore
In a .hgignore, "glob:foo" always means "**/foo". This cannot be
avoided because there is no syntax like "^" in regexes to say you
don't want the implied "**/" (of course one can use regexes, but glob
syntax is nice).
When you have a long list of fairly specific globs like
path/to/some/thing, this has two consequences:
1. unintended files may be ignored (not too common though)
2. matching performance can suffer significantly
Here is vanilla hg status timing on a private repository:
Using syntax:glob everywhere
real 0m2.199s
user 0m1.545s
sys 0m0.619s
When rooting the appropriate globs
real 0m1.434s
user 0m0.847s
sys 0m0.565s
(tangentially, none of this shows up in --profile's output. It
seems that C code doesn't play well with profiling)
The code already supports this but there is no syntax to make use of
it, so it seems reasonable to create such syntax. I create a new
hgignore syntax "rootglob".
