Sure.  This has come up a number of times in the past.

The colon breaks words for the completion system (look at the description
of the COMP_WORDBREAKS shell variable), so when you type

progname :[TAB]

the completion system gets an empty word to complete.  If all of the
possible completions have `:' as the longest common prefix, then the
completion system will insert the colon into the line.
