Previously nothing would be passed to the external command if the query was empty, but the changes in lotabout#217 caused it to instead pass an empty string. This keeps compatibility with the previous behaviour

Surrounds the parameter passed to the
-c/--commandexternal executable with'..'and escapes the string appropriately. This means that when doing interactive grep using ripgrep you can typepub fn my_function_name- a very commonly-needed query - and get the correct result.I assume this wasn't previously done for performance reason, so PR uses my lazy string replacement crate to avoid intermediate allocations. The speed should be pretty good despite escaping, surrounding with quotes and then replacing the
{}(or other-Istring) in the command parameter since that's all done in one pass.From testing on my own computer the speed is very good, but that's just anecdotal evidence.
