Attached is a proposed contribution for the package `tabulated-list.el'.
The idea is to offer to emacs users a feature long-common in GUI
tabulated list widgets - the ability to dynamically resize columns. I
only use emacs in nox, so in my selfishness (and in my ignorance of most
programming things GUI) that's all this function provides, but it's a
start for anyone wanting to extend to that environment.
An obvious follow-up idea is a companion function to change the
sequence of columns, also a long-common feature in GUI environments.
