Describe the bug
The output PO file has comments with a leading period:

#. Your free trial will end on August 6th and will not renew.
#: src/components/routes/billing/Status/Status.tsx:56
msgid "and will not renew."
msgstr ""

To Reproduce
Steps to reproduce the behavior, possibly with minimal code sample, e.g:

import { t } from "@lingui/macro"

cons

When in message value input, make pressing Tab focus the next input in the same language.

Add Ctrl+H shortcut for showing the history dialog.

Right now we only support either a custom message syntax validator or the ICU Message Syntax. We can start to add builtin support for other syntaxes
