Fixed bug #241

Completion behavior has changed from bash-3 to bash-4.  Even the colon
character appears in COMP_WORDBREAKS of both versions, only bash-4 seems to
honor it.  This appears to be a bug in bash-3.  Changes made here work around
the problem so that completion of project names works for either version of
bash.
