The resultant ...-!-join... looks pathological. Is -!- shorthand for some
variable text or is it constant? Can there be white space after -!- but
before the newline? If not then, after placing point somewhere on the
second line, you could wrap some commands in a macro (underscore = space
to make it visible):
C-x (
C-a
M-SPC
Backspace
Backspace
M-SPC
C-r _-
M-SPC
C-x )

If that doesn't do it then you probably have to write something in elisp.
Here are some regexes I use a lot (not programming though, just in text
mode):

C-M-% \(^C-qC-j\)+ RET \1 RET  ;; collapse multiple blank lines into one
C-M-% ^C-qC-j+ RET RET       ;;remove all blank lines
C-M-% _\([;!?]\) RET \1 RET  ;; remove space before sem, bang, quest
C-M-% _+ RET _  RET       ;; collapse all instances of multiple spaces to
one space
