Within the #gentoo channel today I saw today, that the string : (/usr/local/bin:/usr/bin:/bin:/opt/bin:/usr/x86_64-pc-linux-gnu/gcc-bin/4.6.3) was highlighted starting from "bin:/usr/bin". Except that it is even wrong to put the whole path construct into a link /me wonders why only a fraction was converted. Reproducible: Always a screen shot is here : https://bugs.gentoo.org/show_bug.cgi?id=456050
It's a side-effect of short URL recognition (e.g. bit.ly/foo or whatever). Special-casing path context is on the todo.
