setting continuation chars

[gamename]

Hi,

I have a tcl file that uses procedures with lots of parms.
Consequently, I often have to span multiple lines.
Example

blit -a <some parm> -b <some parm> -c <some parm> ...

To span multiple lines, you need to use the backslash ("\") as a
continuation.
Example:

blit \
-a <some parm> \
-b <some parm> \
-c <some parm>

But, I prefer a format where all the backslashes are placed in a
specific column.  It would then look more like this:

blit                  \
-a <some parm>        \
-b <some parm>        \
-c <some parm>

...which makes the continuations obvious.

Is there any way to do one of the following in emacs:

1) automagically put the continuation at a specific column number
OR
2) use some sort of command (regex?) to insert the needed spaces up to
a certain column and then put in a backslash?


TIA,
