Accept non-relative paths for \lilypondfile

[uliska]

Currently the file to be included by \lilypondfile is searched for

• as a relative path appended to CURRFILEDIR
• using kpse.find_file()

I'm not sure about the latter, but I assume it finds the files that LaTeX can find.

In addition it should be possible to find files as

• absolute paths
• paths that are relative to any of the given include paths

Just fixed. Lyluatex looks for input file following this order:

• the file "as is", so that absolute paths work;
• relative to CURRFILEDIR;
• relative to includepaths, following the order of their definition;
• using kpse.find_file() (which you understood well).

I've just pushed another modification: now, the file relative to CURRFILEDIR is searched before the file "as is", because:

• if the given path is absolute, it won't match anyway with CURRFILEDIR, so this doesn't change anything;
• if the given path is relative, a file within the main directory would have had precedence over files relative to the directory of an included tex file, which could have given (in fairly rare cases…) unexpected results.
