• includes fix #463 for v7.2 regression bug in non-SIMD ugrep builds

Notes on unit and regression testing methodology and benchmarking:

• to verify non-SIMD builds I ran 60,000 randomized test patterns each against 100MB text to search and compare to expected matches, this test fully covers the code of the scalar-optimized (non-SIMD) search algorithms (this test was not done for v7.2, which is my fault for thinking the latest change would not impact non-SIMD results, but it did)
• to verify SIMD-optimized builds (SSE2/AVX2/AVX512BW and Neon/AArch64) I ran again 40,000 randomized test patterns each against 100MB text to search and compare to expected matches, this test fully covers the code of the SIMD-optimized search algorithms
• in addition, the RE/flex high-performance regex project also includes many regex pattern test cases
• this release does not affect the search speeds of ugrep v7 i.e. the posted benchmarks for v7 are unchanged
