Append specific lines to a previous line based on sequential search criteria
I'll try explain this as best I can. Let me know if it is not clear.
I have large text files that contain data as such:
Every line in the file that starts with a 9 digit number (followed by a date / time and so on) is a unique message. In the example the first 3 lines are really 1 message (with 2 newlines in it).
This first 9 digit number increments sequentially.
What I want to do is get each message in it's entirety onto 1 line. So I *want* the file to look like:
Note that I'd like there to be a space between the additional lines in a single message.
My first idea was to remove ALL newlines from the file and replace them with spaces, and then work through that data inserting a newline after each of the sequence numbers.
I believe this will solve the problem but unfortunately I don't have the chops to pull it off. I'm sure there are also other, potentially better, ways of solving the problem.
One potential issue, I suppose, would be if one of the "extra" lines in a single message was miraculously the next 9 digit number in the sequence itself. I believe the chances of this would be pretty slim, probably to the extent of making this a moot concern for me at this point... but nonetheless it's something to consider.
Ideally I would like to do this with either perl or bash.

Hi all!
A bit of background: I am trying to create a script that formats SQL statements. I have gotten so far as to add new lines based on certain match criteria like commas, keywords etc. In the process, I end up adding newlines where I don't want.

PAPS(1) General Commands Manual PAPS(1)NAME
paps - UTF-8 to PostScript converter using Pango
SYNOPSIS
paps [options] files...
DESCRIPTION
paps reads a UTF-8 encoded file and generates a PostScript language rendering of the file. The rendering is done by creating outline curves
through the pango ft2 backend.
OPTIONS
These programs follow the usual GNU command line syntax, with long options starting with two dashes (`-'). A summary of options is
included below.
--landscape
Landscape output. Default is portrait.
--columns=cl
Number of columns output. Default is 1.
--font=desc
Set the font description. Default is Monospace 12.
--rtl Do rtl layout.
--paper ps
Choose paper size. Known paper sizes are legal, letter, a4. Default is A4.
--bottom-margin=bm
Set bottom margin in postscript points (1/72 inch). Default is 36.
--top-margin=tm
Set top margin. Default is 36.
--left-margin=lm
Set left margin. Default is 36.
--right-margin=rm
Set right margin. Default is 36.
--help Show summary of options.
--header
Draw page header for each page.
--markup
Interpret the text as pango markup.
--encoding=ENCODING
Assume the documentation encoding is ENCODING.
--lpi Set the lines per inch. This determines the line spacing.
--cpi Set the characters per inch. This is an alternative method of specifying the font size.
--stretch-chars
Indicates that characters should be stretched in the y-direction to fill up their vertical space. This is similar to the texttops
behaviour.
