Automatic shell CR escape \ alignment

[Tracy Reed]

Hello all,

When doing something like:

command -option1 reallylongargument          \
        -option2 evenlongerargumentfoo       \
        -option3 oddlengthreallylongargument \
        -option4 reallylongargument          \

I really like to keep my code to 80 columns and line up those line-ending
escape slashes so it looks neat.  A few years ago someone showed me a really
cool trick to be used when making shell scripts tidy: When in shell mode you
could do something such that it would handle the column of \ in a special way 
and
always keep them lined up and move them all in or out together whenever the
length of the longest line changed. I have forgotten how it was done. Anyone
know?

Thanks!
