This ignores the results of the two writes in sigint handlers even
harder than before.
While my libc lacks the declarations that trigger these warnings, this
can be tested by adding the following to notmuch.h:
__attribute__((warn_unused_result))
ssize_t write(int fd, const void *buf, size_t count);
While all systems that I have access to support strcasestr, it is
in fact not part of POSIX. So here's a fallback reimplementation
based on POSIX functions.
