$ ls
https:__example.com_messages_?folder=other.html
https:__example.com_messages_?folder=pending.html
https:__example.com_messages_?folder=unread.html
M-x compile ls h<TAB>
upon which you will see that M-x compile completion forgets to escape "?"
so one cannot successfully finish completing any of the names.

One gets as far as
Compile command: ls https:__example.com_messages_?folder= [No match]

See how it can't match the stem that it already filled in mostly of for us.
