[TUHS] V7 ls and dot files?

[Aharon Robbins]

Hi All.

The V7 ls.c ignores `.' and `..', unless given the -a option.

The V1 - V6 ls ignores all files that start with `.', unless given -a,
and this is the default for all modern versions of ls.

BWK tells me there's a story about the V7 behavior but he doesn't
remember what it is.  Does anyone here know?

Thanks,

Arnold
