[jazzynico (jazzynico)]

Translation updated in lp:inkscape/0.92.x rev. 15366.
Thanks!

Please don't use < and > signs in the translators credits. Doing so generate an error when checking the file with the check-markup script (I fixed it in the committed file) :
---

is.po: parsing error for `<email address hidden>':
#. TRANSLATORS: Put here your name (and other national contributors')
#. one per line in the form of: name surname (email). Use \n for newline.

msgstr "Sveinn í Felli <email address hidden>, 2014-2017"

Curious; the string [msgstr "Sveinn í Felli <email address hidden>, 2014-2017"] is inserted automatically like this by Lokalize, don't know if other software like Poedit does it too.

And here is an updated Icelandic translation for 0.92.x

Merged from .pot this morning. Please commit to repo.

P.S: should I open a new issue for every update, or can I use the same for updates in the series?
Will make a new one for master.

Regarding opening new issues:
It's fine if you re-use your old issues, but make sure to re-open them (e.g. change status to "In Progress). Otherwise they'll likely get overlooked).

Last note: If you create merge requests on GitHub you can make the process even easier (and likely achieve faster turnaround as merging a MR is typically just a click).
Obviously it's still fine if you prefer to create bugs and attach your updates.
