I just picked a C source code file AT RANDOM from the FreeBSD source tree on the machine I'm using to compose this message (/usr/src/gnu/usr.bin/man/man/glob.c), and I find that, as I expected, it uses exactly that convention. And in that file, the comments don't line up as the author clearly intended unless the tab stops are set every 8 columns. In my experience this is a very common way to assume that tabs will be interpreted. Virtually every source-code file I have encountered since the mid 1970s (for any programming language or operating system) has assumed either this convention or, slightly less often, its 4-column variant. It's surprising that you've never encountered it. -- Alan Bawden -- https://mail.python.org/mailman/listinfo/python-list
