Details:

A while ago I've implemented bit width format conversion specifiers (%d8,
%u64, etc) to strread.m; as strread.m currently is the work horse for
textscan.m, they now also work in textscan.m
AFAICS these changes seem to work fairly reliably. Patch including some tests
attached.

I've also implemented %[] (and %*[], %[^..], %*[^..]) plus %q specifiers in
strread.m (so these will work in textscan, too), but these changes don't work
so very reliably. That is, they do, as long as whitespace and/or delimiters
are not contained in words matching the %q and %[]-like specifiers. In the
tests you can see that in columns matching %[] or %q specifiers the same
number of whitespace/delimiters must be present on each line, otherwise
strread.m quickly loses track.
For my own (simple) purposes it worked OK up till now, but that's no
guarantee.

As advised by Rik I don't develop these patches any further.
I contribute them here just for in case other people want to have a try.
For convenience I've also attached patched strread.m versions in a tarball (
md5sum: 5294a30679a2f6c633f110792da611b7 )
