[Gaim-i18n] help, i was translating old file

[Richard G. <go...@ex...>]

hi, i downloaded http://gaim.sourceforge.net/i18n/sk.po and started 
translating it. Now i have over 50% translated but i found some of the 
strings are missing in this file. The sk.po in gaim 1.5.0 sources is newer 
than the one located on the site. Why? I don't now. You can try it on your 
own if you don't believe. The one on the site has 2247 strings, the one in 
sources 2251.

You can also check 
https://sourceforge.net/tracker/index.php?func=detail&aid=1265359&group_id=235&atid=100235

So, is there any way how not to lose my work and update my translated file 
with missing / changed strings from the newest version?
