startup: do not accept stray characters after a "+" on the command line 

After a "+" only c, r, C, and R are valid characters,
and only when immediately followed by / or ?.

This fixes https://savannah.gnu.org/bugs/?60667.

Bug existed since version 4.4, commit 2326bf6,
since searching at startup with +/ or +? was introduced.
