This commit applies the new canonical formatting style using `clang-format` with custom settings (notably 4-space indentation), as part of our shift toward automated formatting normalization. ⚠️ No functional changes are included — only whitespace and layout modifications as produced by `clang-format`. This change is part of the formatting modernization strategy discussed in: https://github.com/rsyslog/rsyslog/issues/5747 Key context: - Formatting is now treated as a disposable view, normalized via tooling. - The `.clang-format` file defines the canonical style. - A fixup script (`devtools/format-code.sh`) handles remaining edge cases. - Formatting commits are added to `.git-blame-ignore-revs` to reduce noise. - Developers remain free to format code however they prefer locally.

/* smfile.c
|
|
* This is a strgen module for the traditional file format.
|
|
*
|
|
* Format generated:
|
|
* "%TIMESTAMP:::date-rfc3339% %HOSTNAME% %syslogtag%%msg:::sp-if-no-1st-sp%%msg:::drop-last-lf%\n"
|
|
* Note that this is the same as smtradfile.c, except that we do have a RFC3339 timestamp. However,
|
|
* we have copied over the code from there, it is too simple to go through all the hassle
|
|
* of having a single code base.
|
|
*
|
|
* NOTE: read comments in module-template.h to understand how this file
|
|
* works!
