Bump to e42c036.

dmenu: small XmbLookupString code improvements

* Increase the length of composed strings to the same limit as st (32 to 64 bytes).
* Initialize ksym to NoSymbol to be safe: currently this is not an issue though.
* Add comments to clarify the return values of XmbLookupString a bit.

+2022-10-26) project has a different take on patching. It uses preprocessor directives to decide
 whether or not to include a patch during build time. Essentially this means that this build, for
 better or worse, contains both the patched _and_ the original code. The aim being that you can
 select which patches to include and the build will contain that code and nothing more.
