[docs] [issue29928] Add f-strings to Glossary

[Martin Panter]

Martin Panter added the comment:

When I wrote the documentation <https://docs.python.org/dev/reference/lexical_analysis.html#f-strings>, I think I tried to avoid “f-string”, being jargon, and used more formal terminology from PEP 498 instead. But I agree they more than regular literals.

Serhiy do you have a link/message-id/etc of the Python-dev discussion? All I found with Google was <https://www.reddit.com/r/Python/comments/3k969r/lets_find_a_better_name_for_fstrings/>. One other goal is to differentiate these from other formatted strings, such as from str.format and percent formatting.

* formatted strings (doesn’t differentiate from str.format, etc)
* string interpolations
* string expressions
* string comprehensions (apparently too far removed from set comprehensions)
* Maybe format(ted) string displays? (parallelling list etc displays)
