Public bug reported:
Noticed the bug on trusty, still present in
http://bazaar.launchpad.net/~ubuntu-branches/ubuntu/vivid/vte3/vivid/view/head:/src/vte.sh
__vte_prompt_command():
"${PWD/#$HOME/~}" needs to be
"${PWD/#$HOME/\~}"
because ${parameter/pattern/string} does tilde expansion on string.
The bash man page looks like its trying to say that it doesn't happen, but it
does.
In each of the cases below, word is subject to tilde expansion,
parameter expansion, command substitution, and arithmetic
expansion.
Unlike the other things, e.g. ${parameter##word}, ${parameter/pattern/string}
uses "string" instead of "word".
Quoting with a \ should be fine, since quote-removal will get rid of it
even if they change the code to match the docs, and stop doing tilde
expansion on the replacement string.
Also, this is really a separate bug, but /etc/profile.d/* doesn't get sourced
by non-login shells. This makes /etc/profile.d/vte.sh not very useful. There
really ought to be a similar directory for non-login shells. bash-completion
falls victim to this as well.
