347. Minor ECCE oddity when pasting basis sets from BSE: lines longer than 254 chars wreak havoc

Using lines longer than 254 chars when editing nwchem input in ECCE leads to the rest of the input being dropped.

I discovered this when pasting basis sets from bse.pnl.gov. If you paste something which has a line longer than 254 chars, such as the one starting with # H He and ending with valence below (345 chars), everything that comes after that line will be dropped.

To reproduce, set up a calculation. In the editor, click on 'Final Edit'. Now paste your basis set. Save and exit (it's vi/m, so that means using :wq). 

Everything seems to be fine

Now, either select the job and hit Ctrl+I to see the input, or open the editor and click on 'Final Edit' again.

Nothing below the line immediately preceding the long line will be saved. It's not a visualisation issue either -- if you launch the job and do ctrl+o to see what NWChem received as input, it mirrors what you see as input.

Pasting anything other than that overly long line works fine.

A more artificial example would be to try to save this

a
b
abcdefghijklmnopqrstuvxyzabcdefghijklmnopqrstuvxyzabcdefghijklmnopqrstuvxyzabcdefghijklmnopqrstuvxyzabcdefghijklmnopqrstuvxyzabcdefghijklmnopqrstuvxyzabcdefghijklmnopqrstuvxyzabcdefghijklmnopqrstuvxyzabcdefghijklmnopqrstuvxyzabcdefghijklmnopqrstuvxyz1234
d
e

which works, vs this:

a
b
abcdefghijklmnopqrstuvxyzabcdefghijklmnopqrstuvxyzabcdefghijklmnopqrstuvxyzabcdefghijklmnopqrstuvxyzabcdefghijklmnopqrstuvxyzabcdefghijklmnopqrstuvxyzabcdefghijklmnopqrstuvxyzabcdefghijklmnopqrstuvxyzabcdefghijklmnopqrstuvxyzabcdefghijklmnopqrstuvxyz12345
d
e

which doesn't. There's a difference of one character.
