Both SPARC and ARM now expand \t in the assembler window. I've still got
a problem on ARM (i.e. Lazarus running on ARM, not a cross-compiler)
where trying to display the assembler window when at a breakpoint causes
the program to run, things are fine if the window is open before the
program is started.
More details as below. Starting with the assembler window not displayed,
and running to a breakpoint in the source window:

I've saved that file in case you want a copy by e.g. direct mail.
