to .pdf.gz: On a test example (math text with some graphs) perhaps 20 %
savings, it may matter.
to zxpdf: It will never be invoked in the current setup, since the
compressed file gets extracted to temp and is shown from there.
In total, I believe that the suggested changes will make texdoctk work
again.
What remains of this discussion is a question of efficiency. For
instance, it would be sufficient to note only the filename and not the
path in the database. Then the direct lookup of the files could be
removed in favor for the extended search method. In the current
configuration, the latter method will always be called for compressed
files, so efficiency is gained by omitting the first method. The
database file will be smaller as well.
