issue: "glob:" matching not the default in locate

[Sanjoy Mahajan]

[This is the issue that I tried to submit and got the python error:]

The pattern matching in locate is confusing and maybe buggy.  For
example, with this repository:

$ hg manifest | awk '{print $3}'
a/aa/1
a/bb/2
c/3

$ hg locate '**/aa/**'
**/aa/**: No such file or directory
$ hg locate 'glob:**/aa/**'
a/aa/1

So glob: needs to be given, even though the manpage says: "By default,
Mercurial treats file names as shell-style extended glob patterns."

Also I think locate should act like the Linux (solaris?) command of the
same name, which prepends and appends ** (in mercurial notation) to the
pattern if it has no wildcards.  This behavior matches how I mostly use
locate: I half remember a few characters from the filename, perhaps
based on its subject, and I feed the characters to locate.  Then simply
'hg locate aa' does what I want.

$ python -V ; hg --version
