patch 8.2.4687: "vimgrep /\%v/ *" may cause a crash

Problem:    "vimgrep /\%v/ *" may cause a crash.
Solution:   When compiling the pattern with the old engine fails, restore the
            regprog of the new engine instead of leaving it NULL.
            (closes #10079)

+==============================================================================
+14. Language Server Protocol			*language-server-protocol*
+
+The language server protocol specification is available at:
+
+    https://microsoft.github.io/language-server-protocol/specification
+
+Each LSP protocol message starts with a simple HTTP header followed by the
+payload encoded in JSON-RPC format.  This is described in:
+
+    https://www.jsonrpc.org/specification
+
+For messages received on a channel with mode set to "lsp", Vim will process
+the HTTP header and decode the payload into a Vim |Dict| type and call the
+channel callback or the specified callback function.  When sending messages on
+a channel using |ch_evalexpr()| or |ch_sendexpr()|, Vim will add the HTTP
+header and encode the Vim expression into JSON-RPC.
+
+To open a channel using the 'lsp' mode, set the 'mode' item in the |ch_open()|
+{options} argument to 'lsp'.  Example: >
+
+    let ch = ch_open(..., #{mode: 'lsp'})
+
+To open a channel using the 'lsp' mode with a job, set the 'in_mode' and
+'out_mode' items in the |job_start()| {options} argument to 'lsp'. Example: >
+
+    let job = job_start(...., #{in_mode: 'lsp', out_mode: 'lsp'})
+
+To synchronously send a JSON-RPC request to the server, use the |ch_evalexpr()|
+function. This function will return the response from the server. You can use
+the 'timeout' field in the {options} argument to control the response wait
+time. Example: >
+
+    let req = {}
+    let req.method = 'textDocument/definition'
+    let req.params = {}
+    let req.params.textDocument = #{uri: 'a.c'}
+    let req.params.position = #{line: 10, character: 3}
+    let resp = ch_evalexpr(ch, req, #{timeout: 100})
+
+Note that in the request message the 'id' field should not be specified. If it
+is specified, then Vim will overwrite the value with an internally generated
+identifier.  Vim currently supports only a number type for the 'id' field.
+
+To send a JSON-RPC request to the server and asynchronously process the
+response, use the |ch_sendexpr()| function and supply a callback function.
+Example: >
+
+    let req = {}
+    let req.method = 'textDocument/hover'
+    let req.params = {}
+    let req.params.textDocument = #{uri: 'a.c'}
+    let req.params.position = #{line: 10, character: 3}
+    let resp = ch_sendexpr(ch, req, #{callback: 'MyFn'})
+
+To send a JSON-RPC notification message to the server, use the |ch_sendexpr()|
+function. Example: >
+
+    call ch_sendexpr(ch, #{method: 'initialized'})
+
+To respond to a JSON-RPC request message from the server, use the
+|ch_sendexpr()| function.  In the response message, copy the 'id' field value
+from the server request message. Example: >
+
+    let resp = {}
+    let resp.id = req.id
+    let resp.result = 1
+    call ch_sendexpr(ch, resp)
+
+The JSON-RPC notification messages from the server are delivered through the
+|channel-callback| function.
