;; The command automatically removes the indentation ofcurrent line, since

|
|
;; label has to be at the beginning of a line. However, the problem is
|
|
;; that when deleting indentation, trailing spaces are left between the
|
|
;; colon and the original point the colon was inserted.
|
|

|
|
;; These functions solve that problem. First, check whether we have any
|
|
;; space or tab after point. If so, don't do anything because the spaces are
|
|
;; there intentionally. If not, we delete all trailing spaces between
|
|
;; point and colon.
