Precedence: bulk
We had a discussion about filenames end of July. The result was:
1. In TeX (Knuth) the decision was that almost everything, except
a backslash, newline, blank or percent-sign are valid in
filenames, thus not terminating a filename-token after \font,
\input or \openin (Note: this includes {, } and $).
2. Furthermore the kpathsearch-library expands ~, ~uid, $foo and
${foo} like a shell would do (this is system-dependent).
3. You cannot influence the behaviour assigning different catcodes,
\input does not care about catcodes.
As Pierre MacKay already said, although UNIX allows everything in
filenames (even newlines!) it is a bad idea to use it. Because
many programs including TeX make assumptions about separators.
