You can get the updated files here:
http://hg.savannah.gnu.org/hgweb/octave/file/ab0d9d7f479c/scripts/io/textread.m
and
http://hg.savannah.gnu.org/hgweb/octave/file/ab0d9d7f479c/scripts/io/textscan.m

Where to put them?
in an Octave prompt, do:
which textscan

Indeed the fix was to make Octave interpret the "sq-string" value (Single Quoted strings) as a double-quoted one. The vast majority of all other string parameter values are treated similarly in strread.m (textscan's/textread's work horse) but this one had been overlooked.

I should have said that this happens with any single-quoted end-of-line character; but any fix will presumably fix all.

Thanks for fixing.

Fixed on stable branch with this cs:
http://hg.savannah.gnu.org/hgweb/octave/rev/ab0d9d7f479c

Title adapted;
Item group adapted (this was a plain bug, not just ML compatibility).

Confirmed.
Is an easy fix, also required for textread.m

Thx for reporting.

textscan('hello, world; apologies for the inconvenience', '%s%s', 'endofline',"\n");
textscan('hello, world; apologies for the inconvenience', '%s%s', 'endofline','\n');

The first line works; the second, using single quotes for the end-of-line character, fails with an error:

error: textscan: illegal EndOfLine character value specified
error: called from
    textscan at line [y] column [x]
