rxvt -e 'bash -l -i' + use of $LINES & $COLUMNS in .profile

[Hannu E K Nevalainen]

I just want to put this in the archives.

To use $LINES and/or $COLUMNS in the ~/.profile script one has to be aware
that there is a slight delay before they're actually available.

The delay is something like 200ms (P2/450), maybe less, but very much
noticeable if one uses $LINES/$COLUMNS early.

This:

$ head -3 ~/.profile
# Can we make COLUMNS and LINES appear maybe?
echo -en ".\b \b"
kill -SIGWINCH $$

...can help.
