Pull request overview
This pull request implements multi-line EXIT(query) support in interactive mode for go-sqlcmd. When an EXIT command with parentheses is entered and the parentheses are unbalanced, the shell now prompts for continuation lines until the parentheses balance, matching the behavior of ODBC sqlcmd.
Changes:
- Added
isExitParenBalanced()function to check if parentheses in EXIT command arguments are balanced - Added
readExitContinuation()function to prompt for and read continuation lines in interactive mode - Updated
exitCommand()to call continuation logic when parentheses are unbalanced - Added comprehensive test suite for
isExitParenBalanced() - Removed the README limitation note about EXIT(query) not supporting multi-line

In interactive mode, EXIT(query) can now span multiple lines when parentheses are unbalanced. Handles SQL strings, comments, and bracket identifiers correctly. Includes protection against infinite loops (max 1000 continuation lines) and user-friendly error messages for EOF/incomplete commands.

In interactive mode, EXIT(query) can now span multiple lines when parentheses are unbalanced. The shell prompts for continuation lines until parentheses balance, matching ODBC sqlcmd behavior. Adds isExitParenBalanced() function, readExitContinuation() for prompting, updates exitCommand(), adds tests, and removes README limitation note.
