Subject: bug#7229: 23.1; ido guess and ffap bug

Hi, the ffap function of ido mode in emacs makes bad guesses after javadoc-style comments:
/**
and xml node ends
<test />

to reproduce:
emacs -q --no-site-file
M-x ido-mode
M-x customize-option ido-use-filename-at-point
Choose guess, set for current session
open *scratch* buffer

enter /**
cursor at the end of that line
M-x ido-find-file (or C-x f): ido suggests /**, instead of pwd
enter <test />
cursor at the end of that line
M-x ido-find-file (or C-x f): ido suggests /, instead of pwd

same for M-x ffap
