False matches in regexp package - ^/$ matches "/css", yielding "s" #308
Description
by suraci.alex:
Before filing a bug, please check whether it has been fixed since
the latest release: run "hg pull -u" and retry what you did to
reproduce the problem. Thanks.
What steps will reproduce the problem?
1. Compile regexp `^/$`.
2. Dump regexp.MatchStrings("/css");
3.
What is the expected output? What do you see instead?
[]string{} - that is, no match.
Instead, it's matching the last character, returning:
[]string{"s"}
What is your $GOOS? $GOARCH?
src $ env | grep "^GO"
GOBIN=/home/alex/bin
GOARCH=amd64
GOROOT=/home/alex/go
GOOS=linux
Which revision are you using? (hg identify)
src $ hg identify

It didn't do this before (I have it working on 751eaa8f96f7), I'm guessing
the recent regexps overhaul caused it but I really don't know. Tried
changing the match to `^\/$`, since / is often a special regexp character,
but that led to the regexp not compiling at all.
