No, it doesn't... but because of a bug in the refer.xml file that I hadn't notice ! I've fixed that now, thanks to you. Seeing your question, I also had a look at the file /usr/share/mime/packages/freedesktop.org.xml on which such expressions are defined, and it appears that a "%" as first character is used by a lot of files, but usually as part of more longer string -- that's the case of pdf, postcript, postcript fonts, and encapsulated postcript files. The exceptions are matlab and tex files, which can be recognized by a single "%" but with a very low priority of 10. Tex files are better defined, with a priority of 50, if the string "documentclass" begins at the second character. Matlab files are better defined, with a priority of 50, by the string "function" begining at the first character. To avoid most of the conflicts, we can change the priority of the "%" of a refer file: more than 10, and less than 50, so that if a file begins by a "%" it is a refer file, except if that character is part of the definition of another file. WIth such a definition, Tex and Matlab files will not be recognized correctly if 1) they don't have extension, and 2) they only match the single "%" expression. Here is a corrected refer.xml, in wich the bug is fixed, and the priority defined to 40. Cheers, Pierre-Jean.
