mh-msg-num-width-to-column

mh-msg-num-width-to-column is an autoloaded compiled Lisp function in `mh-scan.el'.

(mh-msg-num-width-to-column WIDTH)

Return the column for notations given message number WIDTH.
Note that columns in Emacs start with 0.

If `mh-scan-format-file' is set to "Use MH-E scan Format" this
means that either `mh-scan-format-mh' or `mh-scan-format-nmh' are
in use. This function therefore assumes that the first column is
empty (to provide room for the cursor), the following WIDTH
columns contain the message number, and the column for notations
comes after that.
