Accepting request 1171201 from home:smolsheep:upgrades

Tidied the spec and did some other minor cleanups. Find string borrowed from pip to prevent more rpmlint warnings.
I want to maintain here and in Factory for magic-wormhole.

+%description
+A modern and easy to use streamable zip file generator.
+It can package and stream many files and folders into a zip on the fly
+without needing temporary files or excessive memory.
+
+It can also calculate the final size of the zip file before streaming it.
+
+Features:
+ * Generates zip data on the fly as it's requested.
+ * Can calculate the total size of the resulting zip file before generation even begins.
+ * Low memory usage: Since the zip is generated as it's requested,
+   very little has to be kept in memory (peak usage of less than 20MB is typical, even for TBs of files).
+ * Flexible API: Typical use cases are simple, complicated ones are possible.
+ * Supports zipping data from files, bytes, strings, and any other iterable objects.
+ * Keeps track of the date of the most recently modified file added to the zip file.
+ * Threadsafe: Won't mangle data if multiple threads concurrently add data to the same stream.
+ * Includes a clone of Python's http.server module with zip support added. Try python -m zipstream.server.
+ * Automatically uses Zip64 extensions, but only if they are required.
+ * No external dependencies.
