Research direction
Investigate the bvar source code to find the read command name function. Check where command name is defined and how it is used. The bug suggests a hardcoded limit of 15 characters. Look for a buffer size or string truncation. Consider increasing the limit or using dynamic allocation. Examine comments in the issue for any previous discussion.
