  src/test: Add an extra test case to nxt_term_parse_test.c (2024-09-24 14:55:04 +0100)

----------------------------------------------------------------

The first patch fixes a clang-analyzer and coverity issue where we assign
a value and then assign again without using it inbetween.

The second patch adds a test case for strings with trailing whitespace.
