[Message part 1 (text/plain, inline)]
ffap-latex-mode in ffap.el uses the executable kpsewhich if available. Before a recent change to kpsewhich, the executable would report possible paths, one per line, with no blank lines. Following svn revision 73462 in texlive's tree (which is included in TeX Live 2025; see lines 959-966 at https://svn.tug.org:8369/texlive/trunk/Build/source/texk/kpathsea/kpsewhich.c?r1=69416&r2=73462 ), the new behavior of kpsewhich is to output a blank line for each input file which was not found. The behavior in ffap-latex-mode is to simply take the first line from the temp buffer that recieves the output. Previously, this would either be a valid path, or the buffer would be empty. With the new behavior, the buffer could be non-empty, with various blank lines, and the first valid path might follow after some blank lines. ffap-latex-mode can easily be patched by just removing blank lines from the temp buffer. However I don't know if that is the idiomatic approach; please teach me the ways!
