BUG: 'port cat' appends blank line to svn version of Portfile

[dbevans (David B. Evans)]

When using the command 'port cat port_name' to obtain a copy of a given port's Portfile, the text returned has a blank line appended relative to the svn repository version.

This can be verified as follows:

cp `port dir port_name` Portfile.repo  // get repo copy
port cat port_name > Portfile.cat      // get port cat copy
diff -u Portfile.repo Portfile.cat     // compare them

Using libgweather as an example the result is

--- Portfile.repo       2008-10-10 15:05:03.000000000 -0700
+++ Portfile.cat        2008-10-10 15:05:32.000000000 -0700

This is a problem because if you use 'port cat' to get a presumed copy of a port's Portfile, edit it and then make a patch file for upload to Trac, the patch file will fail when applied to svn if the effect of the patch is to append additional script lines to the end of the original Portfile. If you're not appending to the end, the patch works fine. And, of course, the patch always appears to work fine locally.

This apparently random on again, off again failure mode can cause you to question your sanity (as I was) if you don't recognize the pattern!

I'm using MacPorts built from latest trunk. Haven't tried this with 1.6.0.

Fixed in r40693.

Thanks for the catch, there was also a problem with files larger than 4096 bytes.
