Note: considering that this feature hasn't worked, we may consider removing it
entirely or partially (e.g., escaping) in order to simplify the code, as nobody
has grown used to it. It seems, based on the "hex mode" mentioned in the manual
page, that in the past there was no "normal" search in hex mode, and quoted
strings were the only easy way to look for text. This is no longer the case
nowadays.
Note: the characters in the quoted string are copied out as-is to the regexp.
No regexp-quoting is currently done. We may want to revisit this issue when we
work on ticket #3695.

sscanf() returns EOF when it reaches the end of the string. Our code
erroneously interprets this as if a number was read. The fix: we test for an
explicit '1'.
