Ah, clever.  Then:

mkdir() {
  command mkdir -m $(printf '%o\n' $((01777 - $(umask)))) "$@"
}

This still doesn't address the original poster's concerns if, for
example, a web browser creates a new ~/.browserconf directory the first
time it's invoked.  But nothing bash can do will solve that.

One small problem, though: it doesn't seem to work on all platforms.
(This is with the real mkdir(1).)

imadev:~$ mkdir -m 1755 xyz
imadev:~$ ls -ld xyz
drwxr-xr-x   2 wooledg    pgmr            96 Mar 13 09:20 xyz
imadev:~$ uname -sr
