annotate libinterp/corefcn/oct-stream.cc @ 28183:abcff237241f
Fix textscan handling of empty fields at end of line (Bug #57612).
* oct-stream.cc (skip_whitespace): Change function prototype to have second
argument, EOLstop, default to true.
* oct-stream.cc (textscan_format_list::read_first_row): Add 2nd argument of
false to call to skip_whitespace to reproduce old behavior.
* oct-stream.cc (textscan::skip_delim): Delete unnecessary second argument
of true to skip_whitespace(). Adjust comments for code.
* file-io.cc (Ftextscan): Comment out BIST test for handling of precision which
is already incompatibile with Matlab. Add 3 new BIST tests for bug #57612.
