Combining normal commands and an exe in a map

Dalker on StackOverflow [1] recently helped me concoct this terrific
exe for navigating xdebug traces:
:exe '/^.\{'.(col(".")-1).'\}-'. Before I use it, I must 0f- to ensure
that I am on the first dash of the line. I would like to map this all
to the ` key (I use ' for marks) but I seem to have trouble combining
the regular commands with the exe:
nmap 0f-:exe '/^.\{'.(col(".")-1).'\}-'

Obviously I am missing something, but all my googling turns up
nothing. What keywords should I be googling, or what part of the fine
manual should I be reading? Thanks.
